Did you know there are
dog trailers, PU
slide in dog boxes,
chassis mounted dog rigs, and purposely built
adoption trailers for transporting dogs?
Ever wonder how sled dogs, pack hounds, racing greyhounds, gun dogs, stock dogs, etc get from their home to the events; or rescue dogs get from the kennel/pound to the adoption event in front of a store? People have been coming up with safe solutions for transporting dogs for decades (including in trailers) since there are people who have been transporting more dogs than the typical RVer.
Competing in stock dog events I get to see a wide range of solutions to transporting multiple dogs to events and I get to discuss the pros and cons with those using these solutions.
I periodically see a PU with a 2 level chassis mounted dog box hauling a 2 level dog trailer on the roads here. My guess this rig is transporting a hound pack. We live in an area where there are fox hunts.
